Definitions
- the present invention relates to a modular vertebral stabilizer. More particularly, it relates to a modular vertebral stabilizer that is adapted to connect at least two adjacent vertebrae to each other by using at least two connecting elements which allow some certain limited movement to the vertebrae.
- Vertebral stabilization devices of the static and dynamic types have a screw that is adapted to be connected to a vertebra, and rigid elements or elements that have a limited mobility and have two ends which are jointly connected to the two screws connected to two adjacent vertebrae.
- a dynamic stabilizing device i.e., capable of allowing relative movement between the vertebrae
- This vertebral stabilizer comprises a spacing body, which is resistant to compression and is adapted to transfer forces between two screws implanted in the respective vertebrae, and a tensioning cord which is connected between the two screws described above and passes in an internal longitudinal cavity obtained in the spacing body.
- this stabilizer has a drawback, due to the fact that it is directly assembled locally on the spinal column after inserting the screws in the vertebrae, with open surgery in a space that is close to the vertebra. Therefore, the surgical procedure that makes it possible to use such stabilization structure is highly invasive, since it is necessary to create enough space close to the vertebra to perform the various steps of assembly, with considerable difficulty for the surgeon, who has to arrange and assemble each individual element directly on the vertebra.
- the stabilizer described above does not allow a transverse connection between screws mounted on different vertebrae to transmit forces in a diagonal direction with respect to the axis of the spinal column.
- tensioning cord must be threaded in the spacing body, and this requires a higher skill effort for the surgeon.
- the surgeon may need a stabilizer that has both static and dynamic portions, i.e., he may have to create a hybrid stabilizer, in which the portions can be chosen by the surgeon according to the characteristics of the pathology.
- Known types of stabilizers do not allow creation of a stabilizer of the hybrid type that is totally modular, i.e., capable of adapting to all the configurations that the pathology of the patient may require and are decided on by the surgeon, for example rigid-dynamic-rigid, or dynamic-rigid-dynamic.
- WO2007/060534 in the name of this same Applicant as the present invention, discloses a vertebral stabilizer of the dynamic modular type, which is adapted to be assembled separately from the spinal column and then fitted onto the spinal column in a few seconds.
- the known type of stabilizer device is unable to adapt to angle variations with which the pedicle screws might be fitted within the vertebrae, and therefore, if the positioning of such pedicle screws is not performed, in two adjacent vertebrae, with the same angle, the surgeon encounters difficulties in mounting the stabilizer device fitted over the heads of the pedicle screws.
- the aim of the present invention is to provide a device for stabilizing the spinal column which allows transverse connection between adjacent vertebrae, allowing different angles between pedicle screws inserted in adjacent vertebrae.
- an object of the present invention is to provide a stabilizer device that can be assembled separately from the spinal column and then fitted onto said spinal column with reduced invasiveness for the patient.
- Another object of the present invention is to provide a spinal column stabilizer device that is modular, allowing therefore provision of a hybrid stabilizer device, i.e., a device that is static at one end and dynamic at the opposite end.
- Another object of the present invention is to provide a stabilizer device that is highly reliable, relatively simple to provide and at competitive costs.
- a stabilizer device for the spinal column comprising a first disk-like body and a second disk-like body, which are adapted to be connected to each other by a rod-like element, said first and second disk-like bodies being adapted to be fitted on first and second pedicle screws, which are adapted to be in turn inserted in two adjacent vertebrae, said first and second disk-like bodies being fixable on said pedicle screws, characterized in that said first and second disk-like bodies accommodate bearing means, which are adapted to rotate within said first and second disk-like bodies and to be fitted on said pedicle screws, in order to allow the fitting of said first and second disk-like bodies on said pedicle screws.
- FIG. 1 is an exploded perspective view of a stabilizer device according to the present invention
- FIG. 2 is a perspective view of a second embodiment of the stabilizer device according to the present invention.
- FIG. 3 is a perspective view of the stabilizer device of FIG. 1 in the assembled condition.
- a stabilizer device generally designated by the reference numeral 1 , comprises first and second means for engaging a first pedicle screw 2 and a second pedicle screw 3 , which are adapted to be inserted in two adjacent vertebrae to be connected to each other for mutual stabilization.
- the pedicle screws are conveniently headless and cannulated, so that they can be screwed into the vertebrae.
- First engagement means designated by the reference numeral 4
- second engagement means designated by the reference numeral 5
- First engagement means are adapted to be fitted from above on a threaded portion 6 and 7 respectively on the first pedicle screw 2 and on the second pedicle screw 3 .
- the first and second engagement means 4 and 5 are connected to each other by a rod-like element 8 , of the bar type, which can be made of a rigid material, such as for example titanium, or of softer material, such as for example polyurethane, so as to give flexibility to the rod-like element.
- a rod-like element 8 of the bar type, which can be made of a rigid material, such as for example titanium, or of softer material, such as for example polyurethane, so as to give flexibility to the rod-like element.
- locking means 9 constituted for example by nuts, for locking engagement means 4 and 5 on the threaded portions 6 and 7 of the first and second pedicle screws described earlier.
- the engagement means 4 and 5 comprise a substantially circular body 10 , which is provided with at least one protruding portion 11 , which is adapted to form a seat 12 for the engagement of the rod-like element 8 .
- the seat 12 formed in the protruding portion 11 is conveniently shaped so as to be complementary with respect to the shape of the rod-like element 8 .
- the protruding portion 11 of the circular body 10 is provided with at least one hole 13 , which allows either the insertion of a fastening cord, as defined hereinafter, or of a locking grub, as also described hereinafter.
- the protruding portion 11 can be provided with a second hole arranged on its upper face, i.e., the face designed to be arranged parallel to the spinal column, and is adapted to accommodate a fixing grub, which can allow further fixing of the cord described hereinafter.
- the circular or disk-like element 10 can be provided with a pair of protruding portions 11 , which are diametrically opposite, as shown in FIG. 2 , so as to create an element that is adapted to allow the connection of two rod-like elements, on either side, so as to mutually mate three pedicle screws inserted in three adjacent vertebrae.
- the third pedicle screw in addition to the first and second pedicle screws 2 and 3 , is designated by the reference numeral 15 .
- Such pedicle screws despite having different reference numerals that designate them, are mutually identical.
- FIG. 2 there is also shown the presence of the cord cited above, designated by the reference numeral 16 and made for example of methyl methacrylate, which enters the holes 13 of the circular or disk-like elements 10 and lies in a closed circuit around the rod-like element 8 , which in this case is made of elastic material.
- the two ends of the cord 16 adapted to be mutually coupled so as to provide a cord that is closed in a loop around the rod-like element 8 , are provided with respective tensioning means 17 , which are adapted to allow tensioning of the cord 16 .
- the tensioning means 17 can be provided for example with one end of the cord which is provided with a set of teeth and the opposite end which is provided with a receptacle, like a hose clamp.
- the surgeon can perform, separately from the spinal column, a fastening of the cord 16 around the rod-like element 8 and then, once the stabilizer device has been assembled, said device can be fitted on the pedicle screws that are already accommodated in the holes provided in the vertebrae to be coupled in a stabilized manner.
- the circular or disk-like body 10 is provided internally with a circular opening which accommodates bearing means 20 , which are adapted to rotate within the circular or disk-like body 10 , so as to allow the arrangement of the engagement means 4 at different angles between one screw and the screw that is adjacent to it, thus also allowing a slight positioning error of the pedicle screws inserted in the vertebrae that are to be mutually coupled.
- the bearing 20 is provided with a central hole 21 , which is adapted to allow the insertion of the threaded portion 6 of the pedicle screw 2 or of the threaded portion 7 of the pedicle screw 3 .
- the rod-like element 8 has a circular cross-section with a pair of lateral recesses 22 and 23 which are adapted to accommodate the cord 16 when it is fastened around the rod-like element 8 .
- FIG. 2 shows threaded grubs 24 , which are inserted in the protruding portions 11 of the disk-like bodies 10 so as to fasten the rod-like element 8 .
- FIG. 2 is a view of the provision of a hybrid stabilizer device, i.e., a partly dynamic and partly static stabilizer device, which is obtained by coupling three pedicle screws to each other with a first rod-like element 8 of the rigid type and a second rod-like element 8 of the elastic type, with which the cord 16 fastened around the rod-like element 8 is associated.
- a hybrid stabilizer device i.e., a partly dynamic and partly static stabilizer device, which is obtained by coupling three pedicle screws to each other with a first rod-like element 8 of the rigid type and a second rod-like element 8 of the elastic type, with which the cord 16 fastened around the rod-like element 8 is associated.
- the bearing element 20 accommodated within the hole formed in the disk-like body 10 is adapted to rotate within said hole, so as to behave like a sort of ball that can rotate in all directions within the hole of the disk-like body 10 .
- the stabilizer device according to the present invention fully achieves the intended aim and objects, since it allows to be assembled away from the spinal column, allows to adapt to different implantation angles of the pedicle screws within the vertebrae, and allows to provide hybrid structures with rigid portions and elastic portions.
- this modular system allows to change, whenever necessary, only the disk-like bodies and the bar with a different bar or rod, leaving the screws inserted in the pedicles, with great advantage for the patient and for the surgeon.
- the materials used may be any according to requirements and to the state of the art.
